DETAILED DESCRIPTION

The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses and/or systems described herein. Various changes, modifications, and equivalents of the systems, apparatuses and/or methods described herein will suggest themselves to those of ordinary skill in the art. Descriptions of well-known functions and structures are omitted to enhance clarity and conciseness.

Hereinafter, examples will be described with reference to accompanying drawings in detail.

As shown FIGS. 1 and 2, a heating cabinet 100 includes a body member 110 and a detachable member 120.

The body member 110 has an outer surface formed using transparent material and is configured to form an accommodation space therein, in which an inside of a part surrounding the accommodation space is filled with heat retaining fluid heated by solar energy. The body member 110 receives solar energy and stores heat of the solar energy in the heat retaining fluid not shown, thereby keeping stuffs of the accommodation space warm using the heat. The heat retaining fluid is heated by the solar energy. The heat retaining fluid may be implemented using water.

The detachable member 120 is formed at one side of the body member 110 and is detachable to a window. The detachable member 120 may be implemented using a suction plate. According to an example of coupling the detachable member 120 to the body member 110, coupling holes are formed through the body member 110 and the suction plate is coupled to the coupling holes.

In a state the heating cabinet 100 is attached to a window installed on a wall of offices or houses, if beverage and foods are contained in the heating cabinet 100 during a predetermined time, the beverage and foods are heated up or heated foods are kept warm. In addition, when taking foods contained in the heating cabinet 100, a user may take foods by separating the heating cabinet 100 from the window. Alternatively, a user may separate the heating cabinet from the window and take foods while carrying the separated heating cabinet 100.

Meanwhile, an example of the body member 110 may include an outer body part 111, an inner body part 112 and a sealing part 113.

The outer body part 111 is formed using transparent material. The outer body part 111 may be implemented using transparent plastic.

The inner body part 112 is accommodated in the outer body part 111. The inner body part 112 has a size smaller than that of the outer body part 111. The inner body part 112 may be formed using material having a high thermal conductivity. The inner body part 112 may be implemented using aluminum. For example, each of the outer body part 111 and the inner body part 112 may be provided in the form of a hexahedron having an open upper surface. For example, each of the outer body part 111 and the inner body part 112 may be provided in the form of a cylinder having an open upper surface.

The sealing part 113 is configured to seal an open upper part of a space between the outer part 111 and the inner body part 112 to prevent heat retaining fluid filled between the outer body part 111 and the inner body part 112 from being lost to the outside. The sealing part 113 serves to prevent the heat retaining fluid filled in a space between the outer body part 111 and the inner body part 112 from being lost to the outside.

According to the body member 110 having the structure described above, heat of solar energy is transferred to the heat retaining fluid. The heat accumulated in the heat retaining fluid serves to heat up foods in the accommodation space or keep heated foods warm.

According to another example, the heating cabinet 100 may further include a solar battery part 130 and a heating part not shown.

The solar battery part 130 is formed at one side of the body member 110 to convert solar energy to electric energy.

The heating part is formed at one of the outer body part 111, the inner body part 112, and the heat retaining fluid and is electrically connected to the solar battery part 130. The heating part converts solar energy of the solar battery part 130 to electric energy. The heating part may be implemented using heating coils. The heat produced from the heating coils serves to heat up foods or keep heated food warm.

Meanwhile, the heating cabinet 100 may further include an outlet socket 140. The outlet socket 140 is formed at one side of the outer body part 111. The outlet socket 140 is electrically connected to the solar battery part 130. A plug of home appliances is put into the outlet socket 140. The outlet socket 140 provides electricity of the solar battery part 130 to the home appliances, thereby operating the home appliances.

A number of exemplary embodiments have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents.
